[texts]A detailed description of the sequential probability ratio test for 2-IMU FDI - Rich, T. M
The sequential probability ratio test (SPRT) for 2-IMU FDI (inertial measuring unit failure detection/isolation) is described. The SPRT is a statistical technique for detecting and isolating soft IMU failures originally developed for the strapdown inertial reference unit. The flowchart of a subroutine incorporating the 2-IMU SPRT is included.

[texts]ISCHEMIC HEART DISEASE AND COSMIC RADIATION - KUCHIN, N. N.
A BRIEF EXPOSITION IS PRESENTED OF A THEORY THAT THERE IS A RELATIONSHIP (INVERSE) BETWEEN PEAKS OF COSMIC RADIATION AND EPISODES OF MYOCARDIAL INFARCT AND MEDULLARY INSULT. A BRIEF STATISTICAL ANALYSIS IS GIVEN FOR SELECTED YEARS TO SUPPORT THE HYPOTHESIS, NOT CONSIDERING, HOWEVER, OTHER SEASONAL FACTORS.

[texts]Composite materials, 1 - Fujii, T
The basic definition of a composite material is examined and the main types of composites are characterized. Particle dispersed composite material, fiber reinforced composites (with either discontinuous fibers or continuous fibers arranged unidirectionally or in cross-ply), and laminated composites are considered. Tables are presented showing the mechanical properties (density, tensile strength, specific strength, tensile modulus, and specific modulus) for the most common materials used for fibe...

[texts]Theory of the lifting airscrew - Baskin, V. E.
The vortex theory, and some aspects of velocity potential were discussed. Oblique and axial translations of a lifting airscrew in an ideal fluid are considered first, within the limits of linear and nonlinear theories. Then, viscosity and compressibility effects are introduced. Exposition of some aspects of propeller operation in a compressible medium concludes this presentation.
